PLATFORM SPRING-WAGON GEAR.

SPECIFICATION forming part of Letters Patent No. 349,743, dated September 28, 1886.

Application filed June 14, .1856. Serial No. 205,012. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM L. RAYMENT, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in'Platform Spring-\Vagon Gear; and I do declare the following to be a full and clear description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same, reference being had to the accompanying drawings,

forming a part of this specification.

My invention relates to running-gear of wagons, and especially to platform spring-wagon gear.

The object of this invention is to provide an improved forward running-gear, the springframe of which is light and is strongly braced to resist strains from any direction, and a gear in which expensive circular bolster-plates are dispensed with, and which is so constructed that the forward spring-frame and wagon-bed frame will be held to each other to prevent pitching of the wagon-body when the vehicle travels on uneven roads. I attain these objects by the mechanism illustrated in the accompanying drawings, in which similar letters refer to similar parts throughout the several views.

Figure 1 is a plan view of my device with platform-springs partly broken away and in dotted lines h 71 Fig. 2 is a side view showing platform spring-frame and the manner of trussingthesame. t ional view taken on dotted line 1 1, Fig. 2. Fig. 4 is an enlarged back end View of platform spring-frame, showing sway-bar and antifriotion rollers and spring-block. enlarged plan view of bolster-plates. Fig. 6 is an enlarged sectional view taken on dotted line 2 2, Fig. 4, showing the anti-friction rollers and their bearings. Fig. 7 is a perspective view of spring-block. Fig. 8 is an-inverted perspective ,view of one of the springjaws.

I make the platform spring-frame of four pieces of woodthe center bar, 0, the side bars, D D, and the cross-bar E. The side bars are bolted to the center bar, one on each side, near one end, as shown at Z Z, Fig. 1. The other ends are spread apart to the required width and secured to'the cross-bar E by means Fig. 3 is an enlarged sec-- Fig. 5 is an of clips 0 O, the side bars being bent at m, Fig. 1, said cross-bar being fastened to the front end of the center bar, 0. The side bars and the crossbar are strongly braced by means of the brace-rods b b. by means of'the rod 0, as shown in Fig. 2, one end of which is secured to the side bar at its bend and passing through the eye a, which is formed in the elongated head of the bolt '0, which holds the bolster-plate i, and from the eye 11 the truss extends beneath the plate of the clip 0, and thence forward through the lug (0 on the under side of spring-jaws (I, outside of which lug the truss-rods c 0 receive a tightening-nut, 9. Fig.2 shows only one trussrod, the one on the opposite side being an exact duplicate. V

Arranged as above described, the connected and braced bars 0 D D E make a strong frame capable of resisting heavy strains in any direction.

At the rear end of the platform springframes are located two anti-friction rollers, r and 1-, one above the other, and each having a bearing on stemsv attached to said frame. The upper one, a, is secured by means of the springclips Z Z. The lower one, x, is held by the bolt 8 to the under side of the center bar, 0, and 4 the stem extends rearward through an opening in the spring-block d and rests on the top of the rubber block a, which is placed in the hole 6 in the top of the spring-block d, and to. the wagon-bed frame B (which is pivoted to the spring-frame by means of a kingbolt passin g through said frames and two bolster-plates, the plate f being secured to thewagon-bed frame and the plate i to the platform springframe) is fastened a sway-bar, F, curved to an arc of a circle struck from the point where the two frames are pivoted together, the sway-bar moving between the upper and lower anti-friction rollers, r and "r, the flanges of said rollers running against the front edge of said swaybar, thus preventing said rollers from running off their bearings, the rubber block a holding the rollers and sway-bar in contact.

It will be seen that by using the sway-bar as The side bars are trussed shown and described the expensive circle or fifth-wheel bolster-plates are substituted by the common cheaper straight or flat bolster-plates i and f. Further description is not needed,

as many points are covered by. Letters Patent issued to me October 14, 1884.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In awagon running-gear,thebent side bars D D, center bar, 0, cross-bar E, braces 11 b, the truss-rods c c, and the flanged rolls 1' 1", in combination with the bolster-plates of a pivoted frame, B, carrying a curved SWay bar, F, adapted to form a track for and engage with flanged rolls r r, all combined, arranged, and operating as and for the purpose set forth.

2. The pivoted frame B, carrying arc-bar F, and parts 0 D D E, in combination with the truss c, eyebolt 12, plate 2', springjaws a, lug a, nut 9, rolls 1 1*, spring block d, stems n,
